MUR320S from amsem, in a SMC. Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.
Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | K | passive | Cathode terminal, the end marked by the cathode line on the package, with repetitive peak reverse voltage VRRM of 200 V for the MUR320S. |
| 2 | A | passive | Anode terminal, which carries average forward current Io of 3 A and non-repetitive surge current IFSM of 120 A (60 Hz sine, 1 cycle). |
